Situation

Low-level cold air advecting into an east coast low sitting off the Illawarra coast allowed an extensive and prolonged
period of snow over the central ranges on Tuesday evening and into the night. Snow fell to around 800m AMSL.

A temperature inversion brought about by this cold air is thought to have contributed
in sparing Sydney of forecast dangerous winds. Faster moving air was displaced upwards by the dense, cold air at low levels as it came ashore.

Such a feature is poorly reflected in the available model analysis charts, however they are included here for reference. See the AWN link to the right for
further material.
